as. the table is swung around, the blank ,in the pockets is broughtadjacent the wire spring bending inean'sf located at 16, see

.Fig. l. The wiresp ring tenthsbutton is bent into the shape shown inl ig.

from a single straight length of wire 66, as indi cated in Figs; 20-22. The wire 17 advanced by suitable ineansisnch as rolls 1.8, 18, and ci ed across a pair of arn1s1l, 20,

6-7) pivot i at their middle portion on a bloclrQl. This block movable to and A. series of: pockets 153' j from the table on the base. 3h slide moves to and from the table below block front curved face 2 1, and a rearwardly extending tongue 25, at the base of which are sockets 26 and 27. This has somewhat the contour of the finished spring 28 shown in Fig. 23.

v end wall of a slot in the base will engage The slide 22 is normally pressed rearward by springs 2929, (Fig. 12), and is advanced by a block 30 fast on the plunger 3 (Fig. 5), that engages a cam face 31 of an opening in the slide, to advance the slide from this position to that indicated in Fig. 7. The slide 21 is engaged by a cam piece 32 on the plunger to move it forward, and is movedback by springs 33. The arms 19 and 20 are held in the position shown by a coil spring 34, and at the latter part of the descent of the plunger, a tapered piece 35 on the plunger will engage pins'36 and37 on the arms to separate the rear ends and cause approach. of the forward ends of the arms, as indicated in Fig. 8. The former23 is normally held .to extend above the slide 21 and between the extremities of the arms 19 and 20, that carryears 38 and 39, by a plate spring 40 (Fig. '5) that permits depression of the former by a pin llon the plunger 3 at the latter part of its descent, as shown in Fig.

13. Means are also provided to retain the former in depressed position for a certain period, shown as comprising a pivoted arm 42 (Fig. 14) that is drawn by a coilspring 43 against the former 23 so that when the former is depressed the arm will engage a notch 44in the former and retain the former depressed. (Fig. This is done when the slide 22 has been advanced; and when the slide is returned to normal position, the

the end of the arm 42 and draw it away from the notch bit in the former; whereby the spring 40 will raise-- the former to its normal position. i

Between the table lei and the former 23 is located a spring carrier, shown in the form of a rotatable disc l6, carrying a pinion 47 meshing with the toothed edge 64 of the table. These parts are so designed that when the table is advanced to bring the next pocket 15 into position for operation, the disc will turn a half revolution. The disc has two recesses 48, 49, therein diametrically opposite, and after each advance of the table, one of these recesses will register with a pocket 15 below it on the table, see Fig. 4. These pockets aline with the movement of theslides', and the one remote from the table is normally opposite the former 23, and

adapted to have the former advanced therein by the slide 22. The former and the arms with their ears, serve to bend the-wire length 66 to make the finished spring 28. and force t into the recess in the carrier. The carrier 1 ssam the carrier are a pair of spring-pressed arms or jaws 50, located on top of the disc to slightly overhang the top side edges of the recesses 48, 49, so that the sides of the spring will enter opposed pockets in the cavity. But when it is desired to force the spring down into the table pockets thsc arms or jaws yield and permit engagement by a plunger member with the spring as shown in Fig. 17, the inner edges of the jaws are beveled so as to permit entry of the spring discharging arms 52 described below. licfcrring now particularly to F 5, T, 18 and 19, the means for engaging the linislnid spring, and pushing it out of the recess in the carrier, comprises a downwardly projecting stud 51, carried by the plunger 3. on which is mounted a cylindrical sleeve which is provided with a number of vertical slots, here shown as three in number, to thereby form annular resilient arms The inner part of the stud is reduced, as shown in Fig. 18, and is hollow and slotted to thereby form a pair of annular resilent arms 54.. As the plunger moves downwardly, the outer annular arms 52 will ongage the outer portion of the finished spri while the inner annular arms 5i will or the central portion of the spring to carry the whole spring bodily into the cup. This cup is provided with ahollow central head, slotted at each side is usual; the inner arms 5% push the opposed center portions of the spring over the hollow head so that these portions will snap into the slots in the side of the head.

The button blank is severed from the strip at the location 15, and when the pocket if. in the table is brought around under the car rier, the button blank is slightly lifted to ie ceive the spring 28 inserted by the bar 51.

As shown in Fig. 16, we provide a plunger 55 in the table at this location that will register with the pocket 15 and with the (u rity in the carrier. To reciprocate the plun ger 55 we provide a slide 56 movable in the base to have its inclined portion 57 engage the inclined faces 58 and 59 of a slot in the plunger 55. The slide 56 has an opening with inclined faces (30 and (31 that engage an inclined portion (32 of a bar (33 carried by the plunger When the phuug er I'l descends, this bar will ad mnce the slide 76 and serve to elevate the plunger 55, at the latter portion of the descent of the plunger 3. This will serve to force the button blank up in the pocket 15 to receive the spring 2:1. that will be forced down by the bar 51 hav ing the concentric spring arms.

In the operation of? this machine by the mechanism as set forth, it will be under .nassaaa stood that a thin 'strip or deformable sheet metal is fed into the machine by the rollers 4: and 5, that a head is produced bysuitable dies in the strip, one for each intermittent advance, and that the saws serve to cut. slots in the opposite sides oi the head near its and inserted in the pocket 15.. As the table la is intermittently swung, the button blank will be brought aroundrunder one of the cavities in the carrier 46., The formed spring 28 is at this placeinserted in the :cupped blank, and further advance of: the. table and pockets causes the button blank to pass along and be engaged by finishing dies, not herein set forth, whereby theedge or the cupped blank is rolled over or beaded to retain the spring in the blank.

i The wire 17 is advanced by the rolls 18 to have a length 66 passed across the slides and arms, in front of the former 23adjacent the rounded portion 24:, and back of the cars 38 and 39 on the'arms 19 and 20.

suitable means not shown, the wire. is

severed at theplace 65, leaving a length 66 sufficient to make the finished spring 28 by the bending operation. The slide 22 is first advanced, and the face 24L of the former will engage the wire blank 66 at its middle portion and advance it between the said ears 38, 39, as indicatedin Fig. 4:; that will assume the shape shown in Fig. 20. This position of the bending parts is indicated in Figs. t and 5. Further advance of the slide and former will result in the latter forcing the wire length at its rounded portion into the cavity 48 in the carrier (Figs. (it-7). lhe slide and "former remain in this position at this stage and the continued descent of the plunger 3 will swing the arms 18" and 20, and cause approach of the ears 38 and 89 of the arms, that will bend inwardly the end portions of the blank beyond the rounded portion, againstthe tongue of the former, as indicated in Figs. 8 and 9. The wire length will now assume the form shown 1n Fi The next operation is to cause the advance bodily of the arms 19 and 20, whereby the cars 38 and 39, that now engage the wire blank at the portions 67 and 68 (Fig. 22) will move into the socket portions 26 and 27 of the former (Fi 10),

and bend the wire blank to the form shown carrier cavity. 1

flhe continued ascent of the plunger 3 willresultin the advance of the table, and

rotation of the carrier, that will bring the sprlng blank 28 in the cavity, aroundto the position adjacent the table. It willbe understood that the spring arms 50 will hold the formed spring in the carrier during this travel. This will bring the other recess in the carrier around adjacent the former to have another wire length bent and placed therein at the next descent oi the plunger. While this operation is taking place, the moving down of the plunger 8 will result in the pushing bar 51 with its concentric split end portions enteringthe cavity and serving to spread thcspringpressed arms or jaws 50,and forcing the spring 28 down through the carrier recess and into a cupped blank in the pocket 15 now registering therewith. It will be understood that each descent of the plunger, a wire length is bent and placed in the forward recess of the carrier while, the previously formed wire spring is forced down from the opposite -recess into the button blank.
